Clothing Energy Index™ · CEI

Something is touching your skin every hour you're alive.

You scrutinize what goes in your mouth three times a day. Fabric is against your body twenty-two hours out of twenty-four, and almost nobody has looked at it once.

8

Hours on the same sheets, on the same mattress, breathing the same six inches of air — every single night.

14

Hours in clothing you chose for how it looks, washed in something you chose for how it smells.

The number of those items most people have ever checked the fiber content of.

Your bed is the single longest exposure in your life. It's also the cheapest one to fix.

How the number works

Four questions, asked of everything you wear and sleep on.

CEI isn't about fashion, price, or throwing out your wardrobe. It's about knowing what's actually against you — and most of the score lives in a handful of items you use every day.

01

What is it made of?

Natural fiber, synthetic, or blend — and in what proportion. The label tells you more than the price tag does.

02

What was done to it?

Dyes, wrinkle-resistant and stain-resistant treatments, flame retardants, antimicrobial finishes. Performance always comes from somewhere.

03

What do you wash it in?

Detergent, softener, dryer sheets, fragrance. Whatever you wash with stays in the fiber and sits against skin all day.

04

How long does it touch you?

Contact time is the multiplier. Sheets and underwear carry more weight than a jacket you wear twice a month.

Where the points are

You don't replace a wardrobe. You replace four things.

CEI is the index where the smallest changes move the number most. In order of return:

First

What you wash with

Costs almost nothing, changes every item you own at once, and takes effect the next load. Nothing else in CEI has this ratio.

Second

Sheets and pillowcases

Eight hours of direct contact, including your face. One purchase, one third of your life.

Third

What you sleep in

Whatever you wear to bed is doing eight-hour duty too, and it's usually the oldest thing in the drawer.

Fourth

Base layers

Underwear, socks, anything worn against skin all day. Replace as they wear out rather than all at once.

Later

The mattress

The biggest lever and the biggest expense. Worth knowing about now, worth acting on when it's due for replacement anyway.

You spend a third of your life on one surface. It's worth knowing what it's made of.
